3.8.13.5 -stable review patch. If anyone has any objections, please let me know. ------------------ From: "J. Bruce Fields" <bfields@xxxxxxxxxx> commit 247500820ebd02ad87525db5d9b199e5b66f6636 upstream. A freebsd NFSv4.0 client was getting rare IO errors expanding a tarball. A network trace showed the server returning BAD_XDR on the final getattr of a getattr+write+getattr compound. The final getattr started on a page boundary. I believe the Linux client ignores errors on the post-write getattr, and that that's why we haven't seen this before. Reported-by: Rick Macklem <rmacklem@xxxxxxxxxxx> Signed-off-by: J.
